METHODS, SYSTEMS AND APPARATUSES FOR DISPLAYING REAL-TIME CATHETER POSITION
First Claim
1. A system for tracking and displaying a real-time catheter position overlaying a fluoroscopic image, the system comprising:
- a catheter having an optical coherence tomography (OCT) sensor thereon;
a displacement sensor configured to identify displacement of the catheter; and
a controller configured to;
receive a fluoroscopic image of the distal end of the catheter at a first position; and
determine a displacement of the catheter from the first position to a second position using the displacement sensor; and
a display configured to display the distal end of catheter at the second position as an overlay on the fluoroscopic image.

Abstract
A system for tracking and displaying a real-time catheter position overlaying a fluoroscopic image includes a catheter having an optical coherence tomography (OCT) sensor thereon, a displacement sensor configured to identify displacement of the catheter, a controller, and a display. The controller is configured to receive a fluoroscopic image of the distal end of the catheter at a first position and determine a displacement of the catheter from the first position to a second position using the displacement sensor. The display is configured to display the distal end of catheter at the second position as an overlay on the fluoroscopic image.

28. A catheter device comprising
an elongate body extending from a proximal end to a distal end; -
an optical coherence tomography (OCT) sensor attached to the elongate body; and a displacement sensor attached to the elongate body and axially movable relative to the movable body, the displacement sensor configured to measure a displacement of the distal end of the catheter relative to the displacement sensor; wherein the displacement sensor is configured to be connected to a controller configured to receive signals from the displacement sensor and determine a position of the distal end. - View Dependent Claims (29, 30, 31, 32, 33)
